Adding FEMA WMS to ArcGIS Online

JacobMcGlade

I am able to add the FEMA Web Map Service NFHL through ArcMap and ArcCatalog using the following URL:http://hazards.fema.gov/wmsconnector/wmsconnector/Servlet/NFHL?REQUEST=GetCapabilities&SERVICE=WMS&

I am running into issues adding this same service and/or specific layers to ArcGIS Online through the 'Add Layer from Web' and OGC tabs.

When I input the URL, the layers appear in the legend however no data appears at all scale levels-even after turning every layer on.

Any suggestions on adding layers from the web that do not contain the ArcGIS/rest/services domain?

Any help on this issues or adding other layers from the web is greatly appreciated.  Please provide sample URLs.

I am able to see the Flood Data Availability and Preliminary Maps Issued (I didn't try all layers).

In looking at the capabilities file, it seems like many of the layers have scale dependencies that define scale ranges outside the visible range of ArcGIS Online map viewer. Here's the definition for the Flood Data Availability layer, note the ScaleHint tag.

<Layer queryable="1"><Name>HDM:Q3_COUNTYMAP</Name><Title>Flood Data Availability</Title><SRS>EPSG:4326</SRS><LatLonBoundingBox maxy="71.4062352845" maxx="145.8180850852" miny="-14.3755555272" minx="-178.2175984416"/><ScaleHint max="99999999" min="112.23675100210723"/></Layer>

Here's the definition for another layer that I can't see:

<Layer queryable="1"><Name>Bench_Marks</Name><Title>Bench Marks</Title><SRS>EPSG:4326</SRS><LatLonBoundingBox maxy="64.5106208838" maxx="145.81333305" miny="-14.3733331498" minx="-170.8377777823"/><ScaleHint max="11.971880200624106" min="0"/>

The scaleHint appears to be set at a very large scale. The ArcGIS Map Viewer only goes down to about 1:4500 if you are using the provided basemaps. This layer seems to require a scale of 1:12.  Could there be an error in this WMS?

Thanks,

Mike
